Abstract
Cefixime is an antibiotic from the cephalosporin class used to treat various bacterial infections. The purpose of performing this review is to thoroughly evaluate the pharmacokinetic (PK) data on cefixime.Five databases were systematically searched to identify studies on the PK of cefixime.A total of 38 articles meeting the eligibility criteria were included that provide data on concentration-time profiles or PK parameters such as peak plasma and serum concentration (Cmax), area under the curve (AUC), clearance (CL), and time to reach Cmax (tmax). A dose-dependent increase in AUC and Cmax of cefixime was depicted in healthy volunteers. The clearance of cefixime decreased according to the degree of renal insufficiency among haemodialysis patients. A significant difference in CL was found in comparing fasted and fed states. A biphasic decline in serum concentrations of cefixime was reported when it was taken without probenecid.This review compiles all the reports on the PK of cefixime in healthy and renally impaired patients; the summarized information can be used to optimize cefixime dosing in different disease states. Moreover, cefixime has increased time above MIC value suggesting that it may be an effective treatment for infections caused by certain pathogens.

Abstract
The efficacy of antimicrobial regimens for the treatment of uncomplicated gonococcal urethritis depends partially upon the period of time (therapeutic time) during which the drug concentration in the blood after the concentration peak is greater than four times the minimum inhibitory concentration for 90% of clinical isolates of Neisseria gonorrhoeae (MIC(90)). A therapeutic time of at least 10 h is suggested as an important determinant for elimination of 95% or more of the infection. In this study, therapeutic times for a single 400-mg dose of cefixime at various MIC(90)s were calculated, and pharmacokinetic profiles of double-dosing of 200 mg cefixime at various intervals were simulated. Subsequently, a dosing interval of 6 h was tested in 6 healthy Japanese men, and then 93 Japanese men with gonococcal urethritis were treated with a regimen of two 200-mg doses of cefixime given at a 6-h interval. For a single dose of 400 mg cefixime, therapeutic times were calculated to be 12.8, 9.1, 5.4, and 1.7 h for MIC(90)s of 0.06, 0.125, 0.25, and 0.5 microg/ml, respectively. In the simulation study of double-dosing of 200 mg cefixime at a 6-h interval, the therapeutic times for the MIC(90)s of < or =0.125 microg/ml were longer than 10 h. Of the 93 patients, 68 were evaluated for microbiological outcome, and N. gonorrhoeae was eradicated in 60 (88.2%). The MIC(90) of cefixime for the 61 isolates tested was 0.125 microg/ml. All strains with MICs of < or =0.06 microg/ml were eradicated, whereas 8 of 16 strains with MICs of > or =0.125 microg/ml persisted after treatment. This regimen would not be effective against infection by strains exhibiting cefixime MIC(90)s of > or =0.125 microg/ml. For such strains, a different regimen with a higher dose of cefixime would be required.

Abstract
Cefixime is a third-generation oral cephalosporin that is highly active against a broad range of gram-negative and some gram-positive aerobic bacteria. In non-complicated urinary tract infections it is at least as effective as other usual treatments, and has a low rate of side effects. Several clinical studies have been performed on cefixime in urinary tract infections both in adults and children. On the basis of the literature data, cefixime could be indicated in the treatment of non-complicated urinary tract infections in children either as monotherapy or as switch therapy.

Abstract
The pharmacokinetics of cefixime, a third-generation broad-spectrum cephalosporin, were determined following administration of a 8 mg/kg single oral dose of cefixime suspension to six children with urinary tract infections, ages from 6 to 13 years and weights from 17 to 60 kg. Blood samples for determination of plasma cefixime concentrations were obtained for up to 12 hr and complete urine collections were obtained for urinary excretion of unchanged parent drug for up to 24 hr after administration. Plasma and urine concentrations of cefixime were determined using a reversed phase HPLC assay and pertinent pharmacokinetic parameters were estimated by model-independent standard methods. Mean peak plasma concentration was 4.04 micrograms/ml and was reached after 3.2 hr. The mean area under the plasma concentration-time curve was 33.07 micrograms.hr/ml and the mean elimination half-life was 3.91 hr. The mean apparent total clearance was 4.74 ml/min./kg and about 15% of the dose administered was recovered unchanged in urine. In conclusion, the estimated pharmacokinetic values of cefixime were comparable to those observed in healthy adult subjects based on equivalent mg/ kg doses. Plasma and urine concentrations of the drug were well above the reported minimal plasma and urinary concentrations for most common urinary tract pathogens for up to 12 and 24 hr after administration, respectively.

Abstract
The penetration of oral cefixime into the synovial fluids of 16 patients (mean age, 50.6 years) who underwent joint taps for rheumatic noninfectious disorders was examined. The patients were each given a single dose (400 mg) 2 to 24 h prior to the tap. Cefixime concentrations in serum and joint fluid samples were measured by high-performance liquid chromatography, and the bactericidal activities of these fluids against three isolates each of Haemophilus influenzae and Escherichia coli were examined. The highest concentrations in serum and synovial fluid were achieved 4 h following drug intake, the mean values being 2.8 and 2.03 micrograms/ml, respectively. Effective bactericidal activities (bactericidal titer, > 1:2) against E. coli and H. influenzae were demonstrated in serum and joint fluid up to 10 h following oral intake of cefixime. These results suggest that cefixime penetrates well into joint fluid, achieving levels above the MIC for E. coli lasting as long as 10 h and levels above the MIC for H. influenzae lasting up to 24 h after administration. Good bactericidal activity against susceptible bacterial isolates was observed for at least 10 h after dosing.

Abstract
Cefixime is an orally active third generation cephalosporin with in vitro antibacterial activity against most important lower respiratory pathogens. The drug is active against Haemophilus influenzae, Moraxella catarrhalis and penicillin-susceptible Streptococcus pneumoniae but not Staphylococcus aureus. Cefixime has a long elimination half-life (3 hours compared with 0.5 hours for cefaclor and 1.5 hours for cefalexin), which allows once daily administration. Several trials have established the clinical efficacy of the drug in patients with lower respiratory tract infection (LRTI). In comparative studies cefixime had similar efficacy to amoxicillin +/- clavulanic acid, cefaclor, cefalexin, cefuroxime axetil and clarithromycin. Trials evaluating the efficacy of cefixime as the oral component of intravenous to oral switch therapy have produced promising preliminary results although further carefully designed trials are needed in this area. As with certain other drugs of its class, gastrointestinal disturbances are the most frequently reported adverse events in patients taking cefixime and cases of pseudomembranous colitis have been reported. Thus, cefixime is an effective treatment for mild to moderate LRTI and may have a role as the oral component of intravenous to oral switch therapy although further well designed studies are needed to confirm initial favourable results in this important emerging area of antibacterial therapy.

Abstract
The wide and potent in vitro activity of cefixime, a new oral broad spectrum cephalosporin, has been confirmed on a collection of respiratory and urinary pathogens recently isolated in Italy. The new cephem emerged as the most bactericidal of all the comparators tested against several fast as well as slowly-growing gram-negative species including Enterobacteria, Haemophilus and Moraxella, irrespective of their ability to synthetize beta-lactamases. Among the gram-positive species Streptococcus pyogenes and S. pneumoniae were effectively covered. Cefixime activity was not adversely influenced by several important variables such as pH (over the range from 5 to 8), inoculum size (from 10(5) to 10(8) CFU per ml) and the presence of 50% human serum or urine. Time-kill tests confirmed a pronounced bactericidal potency of the drug especially towards common respiratory pathogens (H. influenzae, M. catarrhalis, S. pneumoniae and S. pyogenes). Killing of urinary strains was optimal at cefixime concentrations reached in urine since eradication, except for Proteus mirabilis, was enhanced with increasing levels of the drug. The absence of an untoward paradoxic effect on the rate of cefixime bactericidal action was confirmed by employing a dynamic bladder model simulating the pharmacokinetic parameters of the drug after a single 200 mg daily dosage. Interactions of cefixime with several other drugs that may be employed in combination therapy were generally prone to provide indifference and synergism while antagonism was never observed. Favorable interactions were also registered when cefixime acted with other antibiotics on partially resistant species such as Staphylococci and Pseudomonas. The new cephem seems to provide excellent opportunities for expanding oral cephalosporin therapy to a wide range of infections produced by susceptible pathogens in the adult and pediatric populations.

Abstract
Cefixime is a new orally active third-generation cephalosporin with a broad spectrum of activity against a variety of both gram-positive and -negative bacteria including many beta-lactamase-producing strains of streptococci, Haemophilus influenzae, Neisseria gonorrhoeae, and the majority of the Enterobacteriaceae. Activity of cefixime against Staphylococcus aureus, enterococci, Listeria monocytogenes, and Pseudomonas spp. is poor. The relatively long elimination half-life of cefixime (approximately 3.0 h) has made possible once- to twice-daily administration with the potential added benefit of improved patient compliance. Clinical trials indicate that cefixime is at least as effective as standard agents in the treatment of genitourinary and upper respiratory tract infections. The incidence of resistant organisms reported during clinical trials with cefixime was low. Adverse reactions observed during clinical trials were relatively uncommon and generally mild and transient in nature. The most significant adverse reactions reported were diarrhea and stool changes occurring in up to 20 percent of patients.

Abstract
A study was performed in 24 healthy male subjects to establish that two suspension formulations of cefixime were bioequivalent to each other and to a reference oral solution. A single 400 mg oral dose of the drug was given in a randomized three-way crossover design as two suspensions (a research suspension (RS) used during clinical trials and a suspension intended for marketing (MS] and a reference oral solution (SOL). Each dose was separated from the other by a 3-day washout period. Mean peak serum concentrations (Cmax) were 4.67, 4.10, and 4.27 micrograms ml-1 after the MS, RS, and SOL, respectively. Although comparison (ANOVA) of the mean pharmacokinetic parameters for cefixime found significant differences (p less than 0.05) in Cmax, the time to Cmax, and area under the serum concentration time curve (AUC 0----infinity) values among the three formulations, the mean differences were less than 20 per cent. No significant differences (p greater than 0.05) were found in either the elimination half-life or renal clearance of unchanged drug. Overall, with a 98 per cent power to detect a 20 per cent difference in AUC0----infinity or urinary recovery values between the formulations tested, the results show that the MS was bioequivalent to the RS and that both suspensions were bioequivalent to the SOL.

Abstract
In a four-way cross-over study, the absolute bioavailability of cefixime was determined in 16 healthy volunteers. Each subject received a single 200-mg dose as an intravenous (IV) and oral solution, and 200-mg and 400-mg capsule doses of the drug. Blood and urine samples were collected for 24 hours after each dose. Cefixime was well tolerated after IV and oral doses of the drug and no serious drug-related adverse effects were observed. The maximal serum concentration (Cmax) of cefixime following the 200-mg oral solution and 200-mg and 400-mg capsule doses were 3.22, 2.92, and 4.84 micrograms/mL, respectively. Mean area under the serum concentration time curves (AUC) following the IV, 200-mg oral solution, and 200-mg and 400-mg capsule doses were 47.0, 26.0, 23.6, and 39.4 micrograms.hr/mL, respectively. Mean elimination half-life values of the drug were comparable after oral and IV doses, ranging from 3.2 to 3.5 hours. Based on serum AUC values, the absolute bioavailability of cefixime was 52.3%, 47.9%, and 40.2% after the 200-mg oral solution, 200-mg capsule and 400-mg capsule doses, respectively. Respective ratios based on 24-hour urinary recovery data were 44.7%, 41.7%, and 40.5%. Therefore, the results show that the percent of cefixime adsorbed after 200-mg and 400-mg oral doses was similar.
